## Monado 24.0.0 (2024-06-07)
This is a substantial release, our first tagged release in three years. In that
intervening period, most Monado users have been using the `main` development
branch directly. We intend to release more regularly going forward, with very
limited backports of fixes to stable branches as needed.
Compared to 21.0.0, this release features, among many other changes,
substantially improved OpenXR conformance, support for additional extensions as
well as initial support for OpenXR 1.1 (intended to be conformant but not yet
submitted), asynchronous time warp in both the graphics-pipeline and
compute-pipeline compositors, equal composition layer support in both compositor
pipelines, improved multi-platform capabilities, optical hand tracking in some
environments, support for external visual-inertial tracking (VIT aka SLAM)
modules, and many driver additions and improvements. The maintainers would like
to express our gratitude to the Monado community for their collective efforts,
submission of merge requests and issues, mutual support, derived runtimes, and
documentation efforts on top of Monado over the past three years. We look
forward to keeping the momentum up!
- Major changes
- Implement OpenXR 1.1
([!2194](https://gitlab.freedesktop.org/monado/monado/merge_requests/2194))
- Added WinMR driver, it supports most headsets and controllers. Controllers can
be connected both via host-Bluetooth and tunneled with the onboard radio chip.
By default has 3DoF tracking, it can do 6DoF if used with the Basalt SLAM
tracking software. Distortion is there but doesn't work perfectly on all
hardware, best results is on Reverb G2.

[!1859](https://gitlab.freedesktop.org/monado/monado/merge_requests/1859))
- New compute-shader based rendering backend in the compositor. Supports
projection, quad, equirect2, cylinder layers. It is not enabled by default.
It also supports ATW. On some hardware the use of a compute queue improves
latency when pre-empting other GPU work.
([!873](https://gitlab.freedesktop.org/monado/monado/merge_requests/873),

[!2001](https://gitlab.freedesktop.org/monado/monado/merge_requests/2001))
- Added [Tracy](https://github.com/wolfpld/tracy) as a supported tracing
backend, it joins the [Perfetto](https://perfetto.dev/) backend. Tracy works
on Windows, but doesn't support full system tracing or multi app as well as
Perfetto.

[!1827](https://gitlab.freedesktop.org/monado/monado/merge_requests/1827))
- Add driver for XREAL (formerly nreal) Air glasses, the device features 3dof
tracking. Also support XREAL Air 2 and XREAL Air 2 Pro.
([!1798](https://gitlab.freedesktop.org/monado/monado/merge_requests/1798),

[#330](https://gitlab.freedesktop.org/monado/monado/issues/330),
[!2172](https://gitlab.freedesktop.org/monado/monado/merge_requests/2172))
- xrt: Updates binding verify usage for new binding code gen and pass in enabled
extensions status.
([!1896](https://gitlab.freedesktop.org/monado/monado/merge_requests/1896))
- Add `libmonado` library, allows control of applications and devices. Exposed
API follows semver and is semi-stable. Will never be changed in a backward
incompatible way without increasing the major version. Provisions for easily
and safely checking version is included, both at compile and runtime.
([!1908](https://gitlab.freedesktop.org/monado/monado/merge_requests/1908),
[!2055](https://gitlab.freedesktop.org/monado/monado/merge_requests/2055),
[!2099](https://gitlab.freedesktop.org/monado/monado/merge_requests/2099))
- Add driver for Rokid and Rokid Max glasses, the devices features 3dof tracking.
([!1930](https://gitlab.freedesktop.org/monado/monado/merge_requests/1930))
- Add new curated debug GUI, while not exposing all the of the knobs it presents
those knobs in a more organized way compared to the advanced UI. The curated UI
also features the readback sink in the background, making it possible for it
to double as the peek window.
([!1941](https://gitlab.freedesktop.org/monado/monado/merge_requests/1941))
- Graphics compositor: Add new graphics layer helper code, supports projection,
quad, cylinder, and equirect2 layers. This path now completely replaces the old
layer renderer that was in the main compositor, making it reusable.
([!1983](https://gitlab.freedesktop.org/monado/monado/merge_requests/1983),
[!1994](https://gitlab.freedesktop.org/monado/monado/merge_requests/1994),
[!1995](https://gitlab.freedesktop.org/monado/monado/merge_requests/1995),
[#299](https://gitlab.freedesktop.org/monado/monado/issues/299),
[!2026](https://gitlab.freedesktop.org/monado/monado/merge_requests/2026),
[!2105](https://gitlab.freedesktop.org/monado/monado/merge_requests/2105))
- Add hot-switch support for input devices like controllers and gamepads. This is
not full hot-plug support, but instead only enables switching between devices
created at start.
([!1992](https://gitlab.freedesktop.org/monado/monado/merge_requests/1992))
- Add framework support for face tracking xrt-devices. XR_HTC_facial_tracking
being the first face tracking extension supported and the conventions of this
for expression weights that xrt-device/drivers can output.
More will be added in the future.
([!2163](https://gitlab.freedesktop.org/monado/monado/merge_requests/2163),
[!2166](https://gitlab.freedesktop.org/monado/monado/merge_requests/2166),
[!2218](https://gitlab.freedesktop.org/monado/monado/merge_requests/2218))
- Add body tracking xrt-devices framework and support for the XR_FB_body_tracking
extension.
([!2178](https://gitlab.freedesktop.org/monado/monado/merge_requests/2178))
- Implement experimental XR_MNDX_xdev_space extension
([!2211](https://gitlab.freedesktop.org/monado/monado/merge_requests/2211),
[!2215](https://gitlab.freedesktop.org/monado/monado/merge_requests/2215))
- XRT Interface
- Added frame timing code that when the underlying vulkan driver supports the
VK_GOOGLE_display_timing extension greatly improves the timing accuracy of
the compositor. Along with this tracing code was added to better help use
understand what was happening during a frame.
([!697](https://gitlab.freedesktop.org/monado/monado/merge_requests/697))
- Add functionality to disable individual drivers in the configuration file.
([!704](https://gitlab.freedesktop.org/monado/monado/merge_requests/704))
- Return `xrt_result_t` from `xrt_gfx_provider_create_gl_egl`.
([!705](https://gitlab.freedesktop.org/monado/monado/merge_requests/705))
- Add `XRT_ERROR_EGL_CONFIG_MISSING` error, to handle missing config from EGL
compositor creation call.
([!705](https://gitlab.freedesktop.org/monado/monado/merge_requests/705),
[!768](https://gitlab.freedesktop.org/monado/monado/merge_requests/768))
- Add small helper function for pushing frames.
([!715](https://gitlab.freedesktop.org/monado/monado/merge_requests/715))
- Add `xrt_compositor_fence` interface to handle service and client render
synchronisation.
([!721](https://gitlab.freedesktop.org/monado/monado/merge_requests/721))
- Add `XRT_ERROR_THREADING_INIT_FAILURE` a new threading related error code.
([!721](https://gitlab.freedesktop.org/monado/monado/merge_requests/721))
- Add alternative functions to `xrt_compositor::wait_frame` called
`xrt_compositor::predict_frame` and `xrt_compositor::mark_frame` these allow
one to do frame timing without having to block on the service side.
([!721](https://gitlab.freedesktop.org/monado/monado/merge_requests/721))
- Add `xrt_multi_compositor_control` that allows the `xrt_system_compositor` to
expose a interface that the IPC layer can use to manage multiple clients
without having to do the rendering. This allows us to move a lot of the code
out the IPC layer and make it more about passing calls.
([!721](https://gitlab.freedesktop.org/monado/monado/merge_requests/721))
- Pass `XrFrameEndInfo::displayTime` to `xrt_compositor::layer_begin` so that the
compositor can correctly schedule frames, most importantly do not display them
too early that might lead to stutter.
([!721](https://gitlab.freedesktop.org/monado/monado/merge_requests/721))
- Make `xrt_swapchain` be reference counted. This will greatly help with
handling swapchains for multiple clients in the compositor rendering pipeline
where a client might go away while the compositor is using it.
([!723](https://gitlab.freedesktop.org/monado/monado/merge_requests/723),
[!754](https://gitlab.freedesktop.org/monado/monado/merge_requests/754),
[!807](https://gitlab.freedesktop.org/monado/monado/merge_requests/807))
- Make `enum xrt_blend_mode` an array instead of a bitfield, so that drivers can
specify which one is preferred.
([!749](https://gitlab.freedesktop.org/monado/monado/merge_requests/749))
- Add new IPC session not created error `XRT_ERROR_IPC_SESSION_NOT_CREATED`, as
some functions cannot be called without first creating a session.
([!768](https://gitlab.freedesktop.org/monado/monado/merge_requests/768))
- Make eye_relation argument to xrt_device_get_view_pose const, more safety for
everybody.
([!794](https://gitlab.freedesktop.org/monado/monado/merge_requests/794))
- Add `XRT_ERROR_IPC_SESSION_ALREADY_CREATED` error message to signal that a
session has already been created on this connection.
([!800](https://gitlab.freedesktop.org/monado/monado/merge_requests/800))
- Add a conventions page.
([!810](https://gitlab.freedesktop.org/monado/monado/merge_requests/810),
[#61](https://gitlab.freedesktop.org/monado/monado/issues/61))
- Send down sub-image offsets and sizes in normalised form, this makes it so that
compositor does not need to track the size of swapchains.
([!847](https://gitlab.freedesktop.org/monado/monado/merge_requests/847))
- Add `use_dedicated_allocation` field to `xrt_image_native` struct to track if
dedicated allocation is required.
([!867](https://gitlab.freedesktop.org/monado/monado/merge_requests/867))
- Add xrt_vec3_f64 struct.
([!870](https://gitlab.freedesktop.org/monado/monado/merge_requests/870))
- Make `xrt_system_compositor_info::supported_blend_modes` an array with an
adjacent count field.
([!975](https://gitlab.freedesktop.org/monado/monado/merge_requests/975))
- Rename all `num_` parameters and fields in the interface, typically to `_count`
but sometimes `_capacity`, to match OpenXR convention.
([!977](https://gitlab.freedesktop.org/monado/monado/merge_requests/977))
- Remove `xrt_view::display::{w|h}_meters`, they are not used anywhere.
([!1054](https://gitlab.freedesktop.org/monado/monado/merge_requests/1054))
- Rename `xrt_space_graph` (and related `m_space_graph_*` functions in
`m_space.h`) to `xrt_relation_chain` to more accurately reflect the function of
this structure.
([!1092](https://gitlab.freedesktop.org/monado/monado/merge_requests/1092))
- Add the ability for `xrt_device` to dynamically change the fov of the views
return back to the applications. We do this by addning a new function called
`xrt_device::get_view_poses` and removing the old one. This function now
returns view poses, fovs and the observer position in one go.
([!1105](https://gitlab.freedesktop.org/monado/monado/merge_requests/1105))
- Add `XRT_TIMEOUT` to be used for operations that can timeout, same value as
`VK_TIMEOUT` for extra compatibility.
([!1147](https://gitlab.freedesktop.org/monado/monado/merge_requests/1147))
- Make it possible when creating the Vulkan client compositor to say if timeline
semaphores has been enabled.
([!1164](https://gitlab.freedesktop.org/monado/monado/merge_requests/1164))
- Add `xrt_compositor_semaphore` object, add interfaces to `xrt_compositor` for
creating the new semaphore object. Also add interface for passing in semaphore
to `xrt_compositor::layer_commit`. Added support for these interface through
the whole Monado stack.
([!1164](https://gitlab.freedesktop.org/monado/monado/merge_requests/1164))
- Add `XRT_CHECK_RESULT` define to be used for ensure that the result from
functions are read and acted upon.
([!1166](https://gitlab.freedesktop.org/monado/monado/merge_requests/1166))
- xrt: Add new `XRT_TRACING` environmental variable to control if tracing is
enabled or not, this is to work around crashes in Perfetto when running the
CTS.
([!1231](https://gitlab.freedesktop.org/monado/monado/merge_requests/1231))
- Introduce `xrt_uuid_t` and `xrt_luid_t` structs and add these as field to
`xrt_system_compositor_info` to more correctly transport UUID and LUID values.
([!1250](https://gitlab.freedesktop.org/monado/monado/merge_requests/1250),
[!1257](https://gitlab.freedesktop.org/monado/monado/merge_requests/1257),
[!1259](https://gitlab.freedesktop.org/monado/monado/merge_requests/1259))
- xrt: Add xrt_swapchain_create_properties to allow client compositors and IPC
code to query the main compositor how many images to create on a swapchain,
and provide an extension point for more properties as needed.
([!1258](https://gitlab.freedesktop.org/monado/monado/merge_requests/1258))
- Introduce `xrt_system_devices` struct and `xrt_instance_create_system` call.
This is a prerequisite for builders, also has the added benefit of moving the
logic of which devices has which role solely into the service/instance.
([!1275](https://gitlab.freedesktop.org/monado/monado/merge_requests/1275),
[!1279](https://gitlab.freedesktop.org/monado/monado/merge_requests/1279),
[!1283](https://gitlab.freedesktop.org/monado/monado/merge_requests/1283),
[!1285](https://gitlab.freedesktop.org/monado/monado/merge_requests/1285),
[!1299](https://gitlab.freedesktop.org/monado/monado/merge_requests/1299))
- Introduce `xrt_builder` struct and various functions on `xrt_prober`
to support them. This is a follow up on the `xrt_system_devices` changes.
These make it much easier to build more complex integrated systems like WinMR
and Rift-S, and moves a lot of contextual configuration out of generic drivers
like the hand-tracker code needing to know which device it was being used by.
([!1285](https://gitlab.freedesktop.org/monado/monado/merge_requests/1285),
[!1299](https://gitlab.freedesktop.org/monado/monado/merge_requests/1299),
[!1313](https://gitlab.freedesktop.org/monado/monado/merge_requests/1313))
- Make an `xrt_builder` specifically for Lighthouse (vive, index, etc.), and
remove Lighthouse devices from the legacy builder.
([!1296](https://gitlab.freedesktop.org/monado/monado/merge_requests/1296))
- No longer include any util headers (in this case `u_time.h`), the XRT headers
are supposed to be completely self contained. The include also messed with
build
refactoring in the auxiliary directory.
([!1328](https://gitlab.freedesktop.org/monado/monado/merge_requests/1328))
- Mark haptic value in xrt_device_set_output as const.
([!1408](https://gitlab.freedesktop.org/monado/monado/merge_requests/1408))
- Remove unused `xrt_layer_cube_data::image_array_index` field.
([!1421](https://gitlab.freedesktop.org/monado/monado/merge_requests/1421))
- Add a single header for limits, like max number of swapchain images.
([!1553](https://gitlab.freedesktop.org/monado/monado/merge_requests/1553))
- Add `XRT_IPC_SERVICE_PID_FILE_NAME` cmake variable to configure the name of pid
file.
([!1567](https://gitlab.freedesktop.org/monado/monado/merge_requests/1567))
- Add `XRT_OXR_RUNTIME_SUFFIX` cmake variable to configure the suffix of the
output openXR library.
([!1567](https://gitlab.freedesktop.org/monado/monado/merge_requests/1567))
- Remove the `xrt_gfx_native.h` as it is no longer needed, it has been replaced
by `compositor/main` own interface file. In the past it was the state tracker
or IPC layer that created the `xrt_system_compositor` directly by calling this
function. But now it's the `xrt_instance`s responsibility, and it can pick
which compositor to create. So this interface becomes less special and just
one of many possible compositors implementations.
([!1569](https://gitlab.freedesktop.org/monado/monado/merge_requests/1569))
- Added `XRT_STRUCT_INIT` define to help with headers and code that needs to
compile as both C and C++ code. This is due to differences in default struct
initialization.
([!1578](https://gitlab.freedesktop.org/monado/monado/merge_requests/1578))
- Document using `XRT_INPUT_GENERIC_UNBOUNDED_SPACE_POSE` unbounded reference
space.
([!1621](https://gitlab.freedesktop.org/monado/monado/merge_requests/1621))
- Remote `xrt_prober_device::product_name` array, the value was only used
internally by the prober. There is already a access function for the product
name that is needed by USB, so make the interface less confusing.
([!1732](https://gitlab.freedesktop.org/monado/monado/merge_requests/1732))
- Added functions to swapchain to explicitly do the barrier insertion. This
pushes the handling of barrier calls into the OpenXR state tracker, while
the changes are minimal for the client compositors they no longer have the
responsibility to implicitly to insert a barrier when needed. Allows us to
in the future support extensions.
([!1743](https://gitlab.freedesktop.org/monado/monado/merge_requests/1743))
- Introduce `xrt_layer_frame_data` struct that holds per frame data for the
`xrt_compositor` layer interface. This is a sibling to the `xrt_layer_data`
struct which holds per layer data. Both are structs instead of arguments to
make it easier to pass the needed data through the layers of Monado, and for
easier extension further down the line.
([!1755](https://gitlab.freedesktop.org/monado/monado/merge_requests/1755))
- Extend `xrt_swapchain_create_properties` to allow the main compositor
request extra bits to be used beyond those requested by the OpenXR app. Some
compositors might need extra usage bits set beyond just the constant sampled
bit. This also ensures that images have exactly the same usages in both the
compositor and app.
([!1763](https://gitlab.freedesktop.org/monado/monado/merge_requests/1763))

extension.
([!1951](https://gitlab.freedesktop.org/monado/monado/merge_requests/1951))
- Add `xrt_limited_unique_id` and `xrt_limited_unique_id_t` types to donate a
special id that is unique to the current process. Use that to decorate
`xrt_swapchain_native` with a limited unique id, useful for caching of the
`xrt_image_native` imports of swapchains and other objects.

availability of the function or feature, only a error condition on bad code.
([!2039](https://gitlab.freedesktop.org/monado/monado/merge_requests/2039))
- handles: Add defines to characterize the behavior of the Vulkan graphics buffer
import functionality: on most platforms, the import consumes the reference, but
on some it just increases a ref count/clones the reference.
([!2042](https://gitlab.freedesktop.org/monado/monado/merge_requests/2042))
- xrt: Improve the xrt_reference helper functions, making them more clear and
better documented.

generic inputs.
([!2048](https://gitlab.freedesktop.org/monado/monado/merge_requests/2048))
- Add reference space usage information, this lets the space overseer know when
a space has been used or no longer used. This allows for doing various things
like recentering when an application starts, or stopping tracking of the floor
if the stage or LOCAL_FLOOR space isn't used.

([!2062](https://gitlab.freedesktop.org/monado/monado/merge_requests/2062))
- Add `xrt_session_event_reference_space_change_pending` event, this is used to
generate `XrEventDataReferenceSpaceChangePending` in OpenXR.
([!2081](https://gitlab.freedesktop.org/monado/monado/merge_requests/2081))
- Pass down broadcast `xrt_session_event_sink` pointer to prober and builder when
creating system, this is used to broadcast events to all sessions. Such as

where given out but we still listed the extension to the loader. So we put it
behind a feature config that is always set to off.
([!1312](https://gitlab.freedesktop.org/monado/monado/merge_requests/1312))
- OpenXR: Make sure to init session fields as early as possible.

- OpenXR: Add disabled `XR_MSFT_hand_intertaction`.
The binding code has support for this extension, but the bindings are not
used in any of the drivers so totally untested and would lead to the wrong
expectations of the applications.

supported in xrSuggestInteractionProfileBindings.
([!2027](https://gitlab.freedesktop.org/monado/monado/merge_requests/2027))
- OpenXR: Make many more extensions build time options, doesn't change which
are enabled by default. This lets runtimes using Monado control which

([!2065](https://gitlab.freedesktop.org/monado/monado/merge_requests/2065))
## Monado 21.0.0 (2021-01-28)
- Major changes
- Adds a initial SteamVR driver state tracker and target that produces a SteamVR
plugin that enables any Monado hardware driver to be used in SteamVR. This is
the initial upstreaming of this code and has some limitations, like only having
working input when emulating a Index controller.
([!583](https://gitlab.freedesktop.org/monado/monado/merge_requests/583))
- XRT Interface
- Add `xrt_binding_profile` struct, related pair structs and fields on
`xrt_device` to allow to move the static rebinding of inputs and outputs into
device drivers. This makes it easier to get a overview in the driver itself
which bindings it can bind to.
([!587](https://gitlab.freedesktop.org/monado/monado/merge_requests/587))
- xrt: Generate bindings for Monado and SteamVR from json.
([!638](https://gitlab.freedesktop.org/monado/monado/merge_requests/638))
- xrt: Introduce `xrt_system_compositor`, it is basically a analogous to
`XrSystemID` but instead of being a fully fledged xrt_system this is only the
compositor part of it. Also fold the `prepare_session` function into the create
native compositor function to simplify the interface.
([!652](https://gitlab.freedesktop.org/monado/monado/merge_requests/652))
- Expose more information on the frameservers, like product, manufacturer and
serial.
([!665](https://gitlab.freedesktop.org/monado/monado/merge_requests/665))
- Add `XRT_FORMAT_BAYER_GR8` format.
([!665](https://gitlab.freedesktop.org/monado/monado/merge_requests/665))
- State Trackers
- st/oxr: Add OXR_FRAME_TIMING_SPEW for basic frame timing debug output.
([!591](https://gitlab.freedesktop.org/monado/monado/merge_requests/591))
- OpenXR: Make sure to restore old EGL display/context/drawables when creating a
client EGL compositor.
([!602](https://gitlab.freedesktop.org/monado/monado/merge_requests/602))
- GUI: Expand with support for controlling the remote driver hand tracking.
([!604](https://gitlab.freedesktop.org/monado/monado/merge_requests/604))
- st/oxr: Implement XR_KHR_vulkan_enable2
([!633](https://gitlab.freedesktop.org/monado/monado/merge_requests/633))
- st/oxr: Add OXR_TRACKING_ORIGIN_OFFSET_{X,Y,Z} env variables as a quick way to
tweak 6dof tracking origins.
([!634](https://gitlab.freedesktop.org/monado/monado/merge_requests/634))
- OpenXR: Be more relaxed with Quat validation, spec says within 1% of unit
length, normalize if not within float epsilon.
([!659](https://gitlab.freedesktop.org/monado/monado/merge_requests/659))
- Drivers
- ns: Fix memory leak in math code.
([!564](https://gitlab.freedesktop.org/monado/monado/merge_requests/564))
- psvr: Rename some variables for better readability.
([!597](https://gitlab.freedesktop.org/monado/monado/merge_requests/597))
- openhmd: Fix viewport calculation of rotated displays.
([!600](https://gitlab.freedesktop.org/monado/monado/merge_requests/600))
- remote: Add support for simulated hand tracking, this is based on the curl
model
that is used by the Valve Index Controller.
([!604](https://gitlab.freedesktop.org/monado/monado/merge_requests/604))
- android: Acquire device display metrics from system.
([!611](https://gitlab.freedesktop.org/monado/monado/merge_requests/611))
- openhmd: Rotate DK2 display correctly.
([!628](https://gitlab.freedesktop.org/monado/monado/merge_requests/628))
- d/psmv: The motor on zcmv1 does not rumble at amplitudes < 0.25. Linear rescale
amplitude into [0.25, 1] range.
([!636](https://gitlab.freedesktop.org/monado/monado/merge_requests/636))
- v4l2: Expose more information through new fields in XRT interface.
([!665](https://gitlab.freedesktop.org/monado/monado/merge_requests/665))
- v4l2: Allocate more buffers when streaming data.
([!665](https://gitlab.freedesktop.org/monado/monado/merge_requests/665))
- IPC
- ipc: Port IPC to u_logging.
([!601](https://gitlab.freedesktop.org/monado/monado/merge_requests/601))
- ipc: Make OXR_DEBUG_GUI work with monado-service.
([!622](https://gitlab.freedesktop.org/monado/monado/merge_requests/622))
- Compositor
- comp: Add basic frame timing information to XRT_COMPOSITOR_LOG=trace.
([!591](https://gitlab.freedesktop.org/monado/monado/merge_requests/591))
- main: Refactor how the compositor interacts with targets, the goal is to enable
the compositor to render to destinations that isn't backed by a `VkSwapchain`.
Introduce `comp_target` and remove `comp_window`, also refactor `vk_swapchain`
to be a sub-class of `comp_target` named `comp_target_swapchain`, the window
backends now sub class `comp_target_swapchain`.
([!599](https://gitlab.freedesktop.org/monado/monado/merge_requests/599))
- Implement support for XR_KHR_composition_layer_equirect (equirect1).
([!620](https://gitlab.freedesktop.org/monado/monado/merge_requests/620),
[!624](https://gitlab.freedesktop.org/monado/monado/merge_requests/624))
- comp: Improve thread safety. Resolve issues in multithreading CTS.
([!645](https://gitlab.freedesktop.org/monado/monado/merge_requests/645))
- main: Lower priority on sRGB format. This works around a bug in the OpenXR CTS
and mirrors better what at least on other OpenXR runtime does.
([!671](https://gitlab.freedesktop.org/monado/monado/merge_requests/671))
- Helper Libraries
- os/time: Make timespec argument const.
([!597](https://gitlab.freedesktop.org/monado/monado/merge_requests/597))
- os/time: Add a Linux specific way to get the realtime clock (for RealSense).
([!597](https://gitlab.freedesktop.org/monado/monado/merge_requests/597))
- math: Make sure that we do not drop and positions in poses when the other pose
has a non-valid position.
([!603](https://gitlab.freedesktop.org/monado/monado/merge_requests/603))
- aux/vk: `vk_create_device` now takes in a list of Vulkan device extensions.
([!605](https://gitlab.freedesktop.org/monado/monado/merge_requests/605))
- Port everything to u_logging.
([!627](https://gitlab.freedesktop.org/monado/monado/merge_requests/627))
- u/hand_tracking: Tweak finger curl model making it easier to grip ingame
objects.
([!635](https://gitlab.freedesktop.org/monado/monado/merge_requests/635))
- math: Add math_quat_validate_within_1_percent function.
([!659](https://gitlab.freedesktop.org/monado/monado/merge_requests/659))
- u/sink: Add Bayer format converter.
([!665](https://gitlab.freedesktop.org/monado/monado/merge_requests/665))
- u/distortion: Improve both Vive and Index distortion by fixing polynomial math.
([!666](https://gitlab.freedesktop.org/monado/monado/merge_requests/666))
- u/distortion: Improve Index distortion and tidy code. While this touches the
Vive distortion code all Vive headsets seems to have the center set to the same
for each channel so doesn't help them. And Vive doesn't have the extra
coefficient that the Index does so no help there either.
([!667](https://gitlab.freedesktop.org/monado/monado/merge_requests/667))
- Misc. Features
- Work toward a Win32 port.

- steamvr: Support HMDs with rotated displays
([!600](https://gitlab.freedesktop.org/monado/monado/merge_requests/600))
## Monado 0.4.1 (2020-11-04)
- State Trackers
- st/oxr: Fix for new conformance tests for xrWaitFrame, xrBeginFrame,
xrEndFrame call order. Also fix OpenXR state transition logic depending on a
synchronized frame loop.
([!589](https://gitlab.freedesktop.org/monado/monado/merge_requests/589),
[!590](https://gitlab.freedesktop.org/monado/monado/merge_requests/590))
## Monado 0.4.0 (2020-11-02)
- XRT Interface
- add `xrt_device_type` to `xrt_device` to differentiate handed controllers
from
controllers that can be held in either hand.
([!412](https://gitlab.freedesktop.org/monado/monado/merge_requests/412))
- Rename functions and types that assumed the native graphics buffer handle type
was an FD: in `auxiliary/vk/vk_helpers.{h,c}` `vk_create_image_from_fd` ->
`vk_create_image_from_native`, in the XRT headers `struct xrt_compositor_fd` ->
`xrt_compositor_native` (and method name changes from `xrt_comp_fd_...` ->
`xrt_comp_native_...`), `struct xrt_swapchain_fd` -> `struct
xrt_swapchain_native`, `struct xrt_image_fd` -> `struct xrt_image_native`, and
corresponding parameter/member/variable name changes (e.g. `struct
xrt_swapchain_fd *xscfd` becomes `struct xrt_swapchain_native *xscn`).
([!426](https://gitlab.freedesktop.org/monado/monado/merge_requests/426),
[!428](https://gitlab.freedesktop.org/monado/monado/merge_requests/428))
- Make some fields on `xrt_gl_swapchain` and `xrt_vk_swapchain` private moving
them into the client compositor code instead of exposing them.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- Make `xrt_compositor::create_swapchain` return xrt_result_t instead of the
swapchain, this makes the methods on `xrt_compositor` more uniform.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- Add the method `xrt_compositor::import_swapchain` allowing a state tracker to
create a swapchain from a set of pre-allocated images. Uses the same
`xrt_swapchain_create_info` as `xrt_compositor::create_swapchain`.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- Make `xrt_swapchain_create_flags` swapchain static image bit match OpenXR.
([!454](https://gitlab.freedesktop.org/monado/monado/merge_requests/454))
- Add `XRT_SWAPCHAIN_USAGE_INPUT_ATTACHMENT` flag to `xrt_swapchain_usage_bits`
so that a client can create a Vulkan swapchain that can be used as input
attachment.
([!459](https://gitlab.freedesktop.org/monado/monado/merge_requests/459))
- Remove the `flip_y` parameter to the creation of the native compositor, this
is
now a per layer thing.
([!461](https://gitlab.freedesktop.org/monado/monado/merge_requests/461))
- Add `xrt_compositor_info` struct that allows the compositor carry information
to about its capabilities and its recommended values. Not everything is hooked
up at the moment.
([!461](https://gitlab.freedesktop.org/monado/monado/merge_requests/461))
- Add defines for underlying handle types.
([!469](https://gitlab.freedesktop.org/monado/monado/merge_requests/469))
- Add a native handle type for graphics sync primitives (currently file
descriptors on all platforms).
([!469](https://gitlab.freedesktop.org/monado/monado/merge_requests/469))
- Add a whole bunch of structs and functions for all of the different layers
in
OpenXR. The depth layer information only applies to the stereo projection
so
make a special stereo projection with depth layer.
([!476](https://gitlab.freedesktop.org/monado/monado/merge_requests/476))
- Add `xrt_image_native_allocator` as a friend to the compositor interface. This
simple interface is intended to be used by the IPC interface to allocate
`xrt_image_native` on the client side and send those to the service.
([!478](https://gitlab.freedesktop.org/monado/monado/merge_requests/478))
- Re-arrange and document `xrt_image_native`, making the `size` field optional.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/493))
- Add const to all compositor arguments that are info structs, making the
interface safer and
more clear. Also add `max_layers` field to the
`xrt_compositor_info` struct.
([!501](https://gitlab.freedesktop.org/monado/monado/merge_requests/501))
- Add `xrt_space_graph` struct for calculating space relations. This struct and
accompanying makes it easier to reason about space relations than just
functions
operating directly on `xrt_space_relation`. The code base is changed
to use
these new functions.
([!519](https://gitlab.freedesktop.org/monado/monado/merge_requests/519))
- Remove the `linear_acceleration` and `angular_acceleration` fields from the
`xrt_space_relation` struct, these were not used in the codebase and are not
exposed in the OpenXR API. They can easily be added back should they be
required again by code or a future feature. Drivers are free to retain this
information internally, but no longer expose it.
([!519](https://gitlab.freedesktop.org/monado/monado/merge_requests/519))
- Remove the `out_timestamp` argument to the `xrt_device::get_tracked_pose`
function, it's not needed anymore and the devices can do prediction better
as
it knows more about its tracking system the the state tracker.
([!521](https://gitlab.freedesktop.org/monado/monado/merge_requests/521))
- Replace mesh generator with `compute_distortion` function on `xrt_device`. This
is used to both make it possible to use mesh shaders for devices and to provide
compatibility with SteamVR which requires a `compute_distortion` function as
well.
The compositor uses this function automatically to create a mesh and
uses mesh
distortion for all drivers. The function `compute_distortion` default
implementations for `none`, `panotools` and `vive` distortion models are
provided in util.
([!536](https://gitlab.freedesktop.org/monado/monado/merge_requests/536))
- Add a simple curl value based finger tracking model and use it for vive and
survive controllers.
([!555](https://gitlab.freedesktop.org/monado/monado/merge_requests/555))
- State Trackers
- OpenXR: Add support for attaching Quad layers to action sapces.
([!437](https://gitlab.freedesktop.org/monado/monado/merge_requests/437))
- OpenXR: Use initial head pose as origin for local space.
([!443](https://gitlab.freedesktop.org/monado/monado/merge_requests/443))
- OpenXR: Minor fixes for various bits of code: copy-typo in device assignment
code; better stub for the unimplemented function
`xrEnumerateBoundSourcesForAction`; better error message on internal error in
`xrGetCurrentInteractionProfile`.
([!448](https://gitlab.freedesktop.org/monado/monado/merge_requests/448))
- OpenXR: Make the `xrGetCurrentInteractionProfile` conformance tests pass,
needed
to implement better error checking as well as generating
`XrEventDataInteractionProfileChanged` events to the client.
([!448](https://gitlab.freedesktop.org/monado/monado/merge_requests/448))
- OpenXR: Centralize all sub-action path iteration in some x-macros.
([!449](https://gitlab.freedesktop.org/monado/monado/merge_requests/449),
[!456](https://gitlab.freedesktop.org/monado/monado/merge_requests/456))
- OpenXR: Improve the validation in the API function for
`xrGetInputSourceLocalizedName`.
([!451](https://gitlab.freedesktop.org/monado/monado/merge_requests/451))
- OpenXR: Implement the function `xrEnumerateBoundSourcesForAction`, currently we
only bind one input per top level user path and it's easy to track this.
([!451](https://gitlab.freedesktop.org/monado/monado/merge_requests/451))
- OpenXR: Properly handle more than one input source being bound to the same
action
according to the combination rules of the specification.
([!452](https://gitlab.freedesktop.org/monado/monado/merge_requests/452))
- OpenXR: Fix multiplicity of bounds paths per action - there's one per
input/output.
([!456](https://gitlab.freedesktop.org/monado/monado/merge_requests/456))
- OpenXR: Implement the MND_swapchain_usage_input_attachment_bit extension.
([!459](https://gitlab.freedesktop.org/monado/monado/merge_requests/459))
- OpenXR: Refactor the native compositor handling a bit, this creates the
compositor earlier then before. This allows us to get the viewport information
from it.
([!461](https://gitlab.freedesktop.org/monado/monado/merge_requests/461))
- OpenXR: Implement action set priorities and fix remaining action conformance
tests.
([!462](https://gitlab.freedesktop.org/monado/monado/merge_requests/462))
- st/oxr: Fix crash when calling `xrPollEvents` when headless mode is selected.
([!475](https://gitlab.freedesktop.org/monado/monado/merge_requests/475))
- OpenXR: Add stub functions and support plumbing for a lot of layer extensions.
([!476](https://gitlab.freedesktop.org/monado/monado/merge_requests/476))
- OpenXR: Be sure to return `XR_ERROR_FEATURE_UNSUPPORTED` if the protected
content bit is set and the compositor does not support it.
([!481](https://gitlab.freedesktop.org/monado/monado/merge_requests/481))
- OpenXR: Update to 1.0.11 and start returning the new
`XR_ERROR_GRAPHICS_REQUIREMENTS_CALL_MISSING` code added in this release.
([!482](https://gitlab.freedesktop.org/monado/monado/merge_requests/482))
- OpenXR: Enable the `XR_KHR_android_create_instance` extension.
([!492](https://gitlab.freedesktop.org/monado/monado/merge_requests/492))
- OpenXR: Add support for creating swapchains with depth formats and submitting
depth layers. The depth layers are passed through to the compositor, but are
not used yet.
([!498](https://gitlab.freedesktop.org/monado/monado/merge_requests/498))
- OpenXR: For pose actions the any path (`XR_NULL_PATH`) needs to be special
cased, essentially turning into a separate action sub path, that is assigned
at
binding time.
([!510](https://gitlab.freedesktop.org/monado/monado/merge_requests/510))
- OpenXR: More correctly implement `xrGetInputSourceLocalizedName` allowing apps
to more accurently tell the user which input to use.
([!532](https://gitlab.freedesktop.org/monado/monado/merge_requests/532))
- OpenXR: Pass through equirect layer data to the compositor.
([!566](https://gitlab.freedesktop.org/monado/monado/merge_requests/566))
- Drivers
- psvr: We were sending in the wrong type of time to the 3DOF fusion code,
switch
to nanoseconds instead of fractions of seconds.
([!474](https://gitlab.freedesktop.org/monado/monado/merge_requests/474))
- rs: Make the pose getting from the T265 be threaded. Before we where getting
the
pose from the update input function, this would cause some the main thread
to
block and would therefore cause jitter in the rendering.
([!486](https://gitlab.freedesktop.org/monado/monado/merge_requests/486))
- survive: Add lighthouse tracking system type
hydra: Add lighthouse tracking
system type
([!489](https://gitlab.freedesktop.org/monado/monado/merge_requests/489))
- rs: Add slam tracking system type
northstar: Use tracking system from tracker
(e.g. rs) if available.
([!494](https://gitlab.freedesktop.org/monado/monado/merge_requests/494))
- psmv: Introduce proper grip and aim poses, correctly rotate the grip pose to
follow the spec more closely. The aim poses replaces the previous ball tip pose
that was used before for aim.
([!509](https://gitlab.freedesktop.org/monado/monado/merge_requests/509))
- survive: Implement haptic feedback.
([!557](https://gitlab.freedesktop.org/monado/monado/merge_requests/557))
- simulated: Tidy the code a bit and switch over to the new
logging API.
([!572](https://gitlab.freedesktop.org/monado/monado/merge_requests/572),
[!573](https://gitlab.freedesktop.org/monado/monado/merge_requests/573))
- psvr: Switch to the new logging API.
([!573](https://gitlab.freedesktop.org/monado/monado/merge_requests/573))
- Add initial "Cardboard" phone-holder driver for Android.
([!581](https://gitlab.freedesktop.org/monado/monado/merge_requests/581))
- IPC
- Generalize handling of native-platform handles in IPC code, allow bi-
directional handle transfer, and de-duplicate code between server and client.
([!413](https://gitlab.freedesktop.org/monado/monado/merge_requests/413),
[!427](https://gitlab.freedesktop.org/monado/monado/merge_requests/427))
- generation: Fix handling 'in_handle' by adding a extra sync round-trip, this
might be solvable by using `SOCK_SEQPACKET`.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- Implement the `xrt_compositor::import_swapchain` function, uses the earlier
`in_handle` work.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- proto: Transport the `xrt_compositor_info` over the wire so that the client can
get the needed information.
([!461](https://gitlab.freedesktop.org/monado/monado/merge_requests/461))
- client: Implement the usage of the `xrt_image_native_allocator`, currently not
used. But it is needed for platforms where for various reasons the allocation
must happen on the client side.
([!478](https://gitlab.freedesktop.org/monado/monado/merge_requests/478))
- client: Add a "loopback" image allocator, this code allocates a swapchain from
the service then imports that back to the service as if it was imported. This
tests both the import code and the image allocator code.
([!478](https://gitlab.freedesktop.org/monado/monado/merge_requests/478))
- ipc: Allow sending zero handles as a reply, at least the Linux fd handling code
allows this.
([!491](https://gitlab.freedesktop.org/monado/monado/merge_requests/491))
- Use a native AHardwareBuffer allocator on the client side when building for
recent-enough Android.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/493))
- ipc: Add functionality to disable a device input via the `monado-ctl` utility,
this allows us to pass the conformance tests that requires the runtime to turn
off a device.
([!511](https://gitlab.freedesktop.org/monado/monado/merge_requests/511))
- Compositor
- compositor: Add support for alpha blending with premultiplied alpha.
([!425](https://gitlab.freedesktop.org/monado/monado/merge_requests/425))
- compositor: Implement subimage rectangle rendering for quad layers.
([!433](https://gitlab.freedesktop.org/monado/monado/merge_requests/433))
- compositor: Enable subimage rectangle rendering for projection layers.
([!436](https://gitlab.freedesktop.org/monado/monado/merge_requests/436))
- compositor: Fix printing of current connected displays on nvidia when no
allowed display is found.
([!477](https://gitlab.freedesktop.org/monado/monado/merge_requests/477))
- compositor: Add env var to temporarily add display string to NVIDIA allowlist.
([!477](https://gitlab.freedesktop.org/monado/monado/merge_requests/477))
- compositor and clients: Use a generic typedef to represent the platform-
specific graphics buffer, allowing use of `AHardwareBuffer` on recent Android.
([!479](https://gitlab.freedesktop.org/monado/monado/merge_requests/479))
- compositor: Check the protected content bit, and return a non-success code if
it's set. Supporting this is optional in OpenXR, but lack of support must be
reported to the application.
([!481](https://gitlab.freedesktop.org/monado/monado/merge_requests/481))
- compositor: Implement cylinder layers.
([!495](https://gitlab.freedesktop.org/monado/monado/merge_requests/495))
- main: Set the maximum layers supported to 16, we technically support more than
16, but things get out of hand if multiple clients are running and all are
using
max layers.
([!501](https://gitlab.freedesktop.org/monado/monado/merge_requests/501))
- main: Add code to check that a format is supported by the GPU before exposing.
([!502](https://gitlab.freedesktop.org/monado/monado/merge_requests/502))
- compositor: Remove panotools and vive shaders from compositor.
([!538](https://gitlab.freedesktop.org/monado/monado/merge_requests/538))
- Initial work on a port of the compositor to Android.
([!547](https://gitlab.freedesktop.org/monado/monado/merge_requests/547))
- render: Implement equirect layer rendering.
([!566](https://gitlab.freedesktop.org/monado/monado/merge_requests/566))
- main: Fix leaks of sampler objects that was introduced in !566.
([!571](https://gitlab.freedesktop.org/monado/monado/merge_requests/571))
- Helper Libraries
- u/vk: Remove unused vk_image struct, this is later recreated for the image
allocator code.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- u/vk: Add a new image allocate helper, this is used by the main compositor to
create, export and import swapchain images.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- u/vk: Rename `vk_create_semaphore_from_fd` to `vk_create_semaphore_from_native`
([!469](https://gitlab.freedesktop.org/monado/monado/merge_requests/469))
- aux/android: New Android utility library added.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/493),
[!547](https://gitlab.freedesktop.org/monado/monado/merge_requests/547),
[!581](https://gitlab.freedesktop.org/monado/monado/merge_requests/581))
- aux/ogl: Add a function to compute the texture target and binding enum for a
given swapchain image creation info.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/493))
- util: Tidy hand tracking header.
([!574](https://gitlab.freedesktop.org/monado/monado/merge_requests/574))
- math: Fix doxygen warnings in vector headers.
([!574](https://gitlab.freedesktop.org/monado/monado/merge_requests/574))
- Misc. Features
- Support building in-process Monado with meson.
([!421](https://gitlab.freedesktop.org/monado/monado/merge_requests/421))
- Allow building some components without Vulkan. Vulkan is still required for the
compositor and therefore the OpenXR runtime target.
([!429](https://gitlab.freedesktop.org/monado/monado/merge_requests/429))
- Add an OpenXR Android target: an APK which provides an "About" activity and
eventually, an OpenXR runtime.
([!574](https://gitlab.freedesktop.org/monado/monado/merge_requests/574),
[!581](https://gitlab.freedesktop.org/monado/monado/merge_requests/581))
- Misc. Fixes
- No significant changes
## Monado 0.3.0 (2020-07-10)
- Major changes
- Centralise the logging functionality in Monado to a single util helper.
Previously most of our logging was done via fprints and gated behind booleans,
now there are common functions to call and a predefined set of levels.
([!408](https://gitlab.freedesktop.org/monado/monado/merge_requests/408),
[!409](https://gitlab.freedesktop.org/monado/monado/merge_requests/409))
- XRT Interface
- compositor: Remove the `array_size` field from the struct, this was the only
state tracker supplied value that was on the struct, only have values that the
compositor decides over on the struct.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- Improve Doxygen documentation of interfaces. Now the inheritance structure and
implementation of interfaces is shown in the docs, and helper functions that
call through function pointers are listed as "member functions", to help
developers understand the internal structure of Monado better.
([!365](https://gitlab.freedesktop.org/monado/monado/merge_requests/365),
[!367](https://gitlab.freedesktop.org/monado/monado/merge_requests/367))
- xrt: Add xrt_result_t return type to many compositor functions that previously
had no way to indicate failure.
([!369](https://gitlab.freedesktop.org/monado/monado/merge_requests/369))
- compositor: Introduce `xrt_swapchain_create_info` simplifying the argument
passing between various layers of the compositor stack and also simplify future
refactoring projects.
([!407](https://gitlab.freedesktop.org/monado/monado/merge_requests/407))
- State Trackers
- OpenXR: Update headers to 1.0.9.
([!358](https://gitlab.freedesktop.org/monado/monado/merge_requests/358))
- OpenXR: Verify that the XrViewConfigurationType is supported by the system as
required by the OpenXR spec in xrEnumerateEnvironmentBlendModes.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Return the correct error code when verifying the sub action, if it is
a
valid sub action path but not given at action creation we should return
`XR_ERROR_PATH_UNSUPPORTED`.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Validate the subImage data for both projection and quad layers layers,
refactor code out so it can be shared with the different types of layers. Need
to track some state on the `oxr_swapchain` in order to do the checking.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Correct the return error code for action and action set localized name
validation.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Correct the error messages on sub action paths errors.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Track the name and localized name for both actions and action sets,
that
way we can make sure that there are no duplicates. This is required by the
spec. ([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Do better checking if action sets and actions have been attached to the
session or not.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Validate the arguments for `xrSuggestInteractionProfileBindings` better
so that it follows the spec better.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Rework the logging formatting of error messages, this makes it easier
to
read for the application developer.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Correctly ensure that the application has called the required get
graphics requirements function when creating a session.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: When an `XrSession` is destroyed purge the event queue of any events
that
references to it so that no events gets delivered to the applications with
stales handles.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Make the event queue thread safe, all done with a simple mutex that is
not held for long at all.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: A major overhaul of the swapchain acquire, wait and release code. This
makes it almost completely conformant with the spec. Tricky parts include that
multiple images can be acquired, but only one can be waited on before being
released.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Enforce that static swapchains can only be acquired once, this is
required by the spec and make sure that a image is only rendered to once, and
allows the runtime to perform special optimizations on the image.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Make the function `xrGetReferenceSpaceBoundsRect` at least conform to
the spec without actually implementing it, currently we do not track bounds in
Monado.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Make the session state changes obey the specification. The code is
fairly hair as is and should be improved at a later time.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Use the correct XrPath for `/user/gamepad` while it sits in the users
hand itsn't `/user/hand/gamepad` as previously believed.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- OpenXR: Where used make sure we verify the view configuration type is a valid
enum value, the code is setup so that we in the future can support new values
via extensions easily.
([!368](https://gitlab.freedesktop.org/monado/monado/merge_requests/368))
- OpenXR: More correctly verify the interactive profile binding data, including
the given interactive profile is correct and the binding point is valid.
([!377](https://gitlab.freedesktop.org/monado/monado/merge_requests/377))
- OpenXR: Transform input types in a somewhat flexible, composable way. Also, do
conversion at sync time, and use the transformed values to evaluate if the
input has changed, per the spec.
([!379](https://gitlab.freedesktop.org/monado/monado/merge_requests/379))
- OpenXR: Tidy the extensions generated by the script and order them according
to
extension prefix, starting with KHR, EXT, Vendor, KHRX, EXTX, VendorX. Also
rename the `MND_ball_on_stick_controller` to `MNDX_ball_on_a_stick_controller`.
([!410](https://gitlab.freedesktop.org/monado/monado/merge_requests/410))
- OpenXR: Fix overly attached action sets, which would appear to be attached to
a
session even after the session has been destroyed. Also tidy up comments and
other logic surrounding this.
([!411](https://gitlab.freedesktop.org/monado/monado/merge_requests/411))
- Drivers
- psvr: Normalize the rotation to not trip up the client app when it gives the
rotation back to `st/oxr` again.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- vive: Create vive_config module to isolate config code and avoid duplication
between controller and headset code.
vive: Probe for controllers in vive_proper
interface.
vive: Fix a bug where using the Vive Pro crashed Monado.
vive: Fix a
bug where the controller didn't parse JSON vectors correctly.
vive: Move
missing functions to and use u_json.
([!405](https://gitlab.freedesktop.org/monado/monado/merge_requests/405))
- vive: Add support for Gen1 and Gen2 Vive Trackers.
([!406](https://gitlab.freedesktop.org/monado/monado/merge_requests/406))
- vive: Port to new u_logging API.
([!417](https://gitlab.freedesktop.org/monado/monado/merge_requests/417))
- comp: Set a compositor window title.
([!418](https://gitlab.freedesktop.org/monado/monado/merge_requests/418))
- IPC
- server: Almost completely overhaul the handling of swapchain lifecycle
including: correctly track which swapchains are alive; reuse ids; enforce the
maximum number of swapchains; and destroy underlying swapchains when they are
destroyed by the client.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- util: Make sure to not dereference NULL control messages, say in the case of the
server failing to create a swapchain. Also add a whole bunch of paranoia when
it comes to the alignment of the control message buffers.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- ipc: Return XR_ERROR_INSTANCE_LOST on IPC errors.
([!369](https://gitlab.freedesktop.org/monado/monado/merge_requests/369))
- Compositor
- main: Include `<math.h>` in layers renderer for missing `tanf` function.
([!358](https://gitlab.freedesktop.org/monado/monado/merge_requests/358))
- swapchain: Give out the oldset image index when a image is acquired. This logic
can be made better, but will work for the good case.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- swapchain: Close any FDs that are still valid, for instance the ipc server
copies the FDs to the client.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- client: When we give a image fd to the either OpenGL or Vulkan it is consumed
and cannot be reused. So make sure that it is set to an invalid fd value on the
`xrt_image_fd` on the owning `xrt_swapchain_fd`.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- main: We were alpha blending all layers previously, but now we support the
layer flag that OpenXR gives us. We do this by using different `VkImageView`s
with different component swizzles.
([!394](https://gitlab.freedesktop.org/monado/monado/merge_requests/394))
- layer_rendering: Use the visibility flags on quad to correctly show the layers
in each eye.
([!394](https://gitlab.freedesktop.org/monado/monado/merge_requests/394))
- Helper Libraries
- os/threading: Include `xrt_compiler.h` to fix missing stdint types.
([!358](https://gitlab.freedesktop.org/monado/monado/merge_requests/358))
- util: Add a very simple fifo for indices, this is used to keep track of
swapchain in order of age (oldness).
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- util: Expand `u_hashset` to be able to automatically allocate a `u_hashet_item`
and insert it.
([!359](https://gitlab.freedesktop.org/monado/monado/merge_requests/359))
- Misc. Features
- build: Allow enabling inter-procedural optimization in CMake GUIs, if supported
by platform and compiler.
([!330](https://gitlab.freedesktop.org/monado/monado/merge_requests/330))
- Misc. Fixes
- No significant changes
## Monado 0.2 (2020-05-29)
- Major changes
- Add support for a new service process. This process houses the hardware drivers
and compositor. In order to do this, a whole new subsection of Monado called
ipc
was added. It lives in `src/xrt/ipc` and sits between the state trackers
and
the service hosting the drivers and compositor.
([!295](https://gitlab.freedesktop.org/monado/monado/merge_requests/295))
- Support optional systemd socket-activation: if not disabled at configure time,
`monado-service` can be launched by systemd as a service with an associated
socket. If the service is launched this way, it will use the systemd-created
domain socket instead of creating its own. (If launched manually, it will still
create its own as normal.) This allows optional auto-launching of the service
when running a client (OpenXR) application. Associated systemd unit files are
also included.
([!306](https://gitlab.freedesktop.org/monado/monado/merge_requests/306))
- XRT Interface
- Add a new settings interface for transporting camera settings, in
`xrt/xrt_settings.h`.
([!266](https://gitlab.freedesktop.org/monado/monado/merge_requests/266))
- Make it possible to send JSON object to drivers when probing for devices.
([!266](https://gitlab.freedesktop.org/monado/monado/merge_requests/266))
- Added new `xrt_instance` object to be root object, a singleton that allows us
to
better swap out the whole stack underneath the state trackers. This is now
implemented by the `xrt_prober` code and used by the OpenXR state tracker.
([!274](https://gitlab.freedesktop.org/monado/monado/merge_requests/274))
- Remove the `struct timestate` argument from the `struct xrt_device` interface.
It should be easy to write a driver and the state tracker should be the one
that tracks this state. It was mostly triggered by the out of process
compositor work.
([!280](https://gitlab.freedesktop.org/monado/monado/merge_requests/280))
- Add the new format `XRT_FORMAT_UYVY422` to the interface and various parts of
the code where it is needed to be supported, like the conversion functions and
calibration code. Also rename the `XRT_FORMAT_YUV422` to `XRT_FORMAT_YUYV422`.
([!283](https://gitlab.freedesktop.org/monado/monado/merge_requests/283))
- Expose manufacturer and serial number in the prober interface, right now only
for the video device probing. But this is the only thing that really requires
this in order to tell different cameras apart.
([!286](https://gitlab.freedesktop.org/monado/monado/merge_requests/286))
- Add `XRT_CAST_PTR_TO_OXR_HANDLE` and `XRT_CAST_OXR_HANDLE_TO_PTR` macros to
perform warning-free conversion between pointers and OpenXR handles, even on
32-bit platforms. They should be used instead of raw casts.
([!294](https://gitlab.freedesktop.org/monado/monado/merge_requests/294))
- Remove declaration and implementations of `xrt_prober_create`: the minimal
functionality previously performed there should now be moved to

into a atom and keep all created paths in a array.
([!349](https://gitlab.freedesktop.org/monado/monado/merge_requests/349))
- OpenXR: Give better error messages on invalid poses in quad layers instead of
using the simple macro.
([!350](https://gitlab.freedesktop.org/monado/monado/merge_requests/350))

([!270](https://gitlab.freedesktop.org/monado/monado/merge_requests/270))
- main: Split RandR and NVIDIA direct mode window back ends.
([!271](https://gitlab.freedesktop.org/monado/monado/merge_requests/271))
- main: Improve synchronization and remove redundant vkDeviceWaitIdle calls.
([!277](https://gitlab.freedesktop.org/monado/monado/merge_requests/277))
- main: Delay the destruction of swapchains until a time where it is safe, this
allows swapchains to be destroyed from other threads.
([!278](https://gitlab.freedesktop.org/monado/monado/merge_requests/278))
- client: Propagate the supported formats from the real compositor to the client
ones. ([!282](https://gitlab.freedesktop.org/monado/monado/merge_requests/282))

- main: Only allocate one image for static swapchains.
([!349](https://gitlab.freedesktop.org/monado/monado/merge_requests/349))
- Helper Libraries
- tracking: Add image undistort/normalize cache mechanism, to avoid needing to
remap every frame.
([!255](https://gitlab.freedesktop.org/monado/monado/merge_requests/255))
- tracking: Improve readability and documentation of IMU fusion class.
([!255](https://gitlab.freedesktop.org/monado/monado/merge_requests/255))
- u/file: Add file helpers to load files from config directory.
([!266](https://gitlab.freedesktop.org/monado/monado/merge_requests/266))
- u/json: Add bool getter function.
([!266](https://gitlab.freedesktop.org/monado/monado/merge_requests/266))

([!266](https://gitlab.freedesktop.org/monado/monado/merge_requests/266))
- tracking: Remove all path hardcoded calibration data loading and saving
functions.
([!266](https://gitlab.freedesktop.org/monado/monado/merge_requests/266))
- threading: New helper functions and structs for doing threaded work, these are
on a higher level then the one in os wrappers.
([!278](https://gitlab.freedesktop.org/monado/monado/merge_requests/278))

([!282](https://gitlab.freedesktop.org/monado/monado/merge_requests/282))
- u/time: Temporarily disable the time skew in time state and used fixed offset

([!348](https://gitlab.freedesktop.org/monado/monado/merge_requests/348))
- math: Correctly validate quaternion using non-squared "length" instead of

([!233](https://gitlab.freedesktop.org/monado/monado/merge_requests/233),
[!237](https://gitlab.freedesktop.org/monado/monado/merge_requests/237),
[!238](https://gitlab.freedesktop.org/monado/monado/merge_requests/238),
[!240](https://gitlab.freedesktop.org/monado/monado/merge_requests/240))
- os/ble: Add utility functionality for accessing Bluetooth Low-Energy (Bluetooth
LE or BLE) over D-Bus, in `os/os_ble.h` and `os/os_ble_dbus.c`.
([!242](https://gitlab.freedesktop.org/monado/monado/merge_requests/242))
- util: Add some bit manipulation helper functions in `util/u_bitwise.c` and
`util/u_bitwise.c`.
([!242](https://gitlab.freedesktop.org/monado/monado/merge_requests/242))
- tracking: Make stereo_camera_calibration reference counted, and have the
prober,
not the calibration, call the save function.
([!245](https://gitlab.freedesktop.org/monado/monado/merge_requests/245))

([!252](https://gitlab.freedesktop.org/monado/monado/merge_requests/252))
- build: Support building with system cJSON instead of bundled copy.
([!284](https://gitlab.freedesktop.org/monado/monado/merge_requests/284),
[#62](https://gitlab.freedesktop.org/monado/monado/issues/62))
- ci: Perform test builds using the Android NDK (for armeabi-v7a and armv8-a).
This is not a full Android port (missing a compositor, etc) but it ensures we
don't add more Android porting problems.
([!292](https://gitlab.freedesktop.org/monado/monado/merge_requests/292))
- Misc. Fixes
- os/ble: Check if `org.bluez` name is available before calling in
`os/os_ble_dbus.c`.
([#65](https://gitlab.freedesktop.org/monado/monado/issues/65),
[#64](https://gitlab.freedesktop.org/monado/monado/issues/64),
[!265](https://gitlab.freedesktop.org/monado/monado/merge_requests/265))
- README: Added information to the README containing OpenHMD version requirement
and information regarding the requirement of `GL_EXT_memory_object_fd` and
limitations on Monado's compositor.
([!4](https://gitlab.freedesktop.org/monado/monado/merge_requests/4))

probing for BLE devices.
([!247](https://gitlab.freedesktop.org/monado/monado/merge_requests/247))
- d/dd: Use the correct time delta in DayDream driver.
([!249](https://gitlab.freedesktop.org/monado/monado/merge_requests/249))

([!258](https://gitlab.freedesktop.org/monado/monado/merge_requests/258))
- os/ble: Fix leak in `os/os_ble_dbus.c` code when failing to find any device.
([!264](https://gitlab.freedesktop.org/monado/monado/merge_requests/264))
- os/ble: Make ble code check for some error returns in `os/os_ble_dbus.c`.
([!265](https://gitlab.freedesktop.org/monado/monado/merge_requests/265))
- u/hashset: Fix warnings in `util/u_hashset.h` after pedantic warnings were
enabled for C++.
([!268](https://gitlab.freedesktop.org/monado/monado/merge_requests/268))
- build: Fix failure to build from source on ppc64 and s390x.
([!284](https://gitlab.freedesktop.org/monado/monado/merge_requests/284))
- build: Mark OpenXR runtime target in CMake as a MODULE library, instead of a
SHARED library.
([!284](https://gitlab.freedesktop.org/monado/monado/merge_requests/284))
- windows: Way way back when Gallium was made `auxiliary` was named `aux` but
then
it was ported to Windows and it was renamed to `auxiliary` since Windows
is [allergic to filenames that match its device names](https://docs.microsoft.com/en-us/windows/win32/fileio/naming-a-file#naming-conventions)
(e.g., `AUX`, `CON`, `PRN`, etc.). Through the ages, this knowledge was lost
and so we find ourselves with the same problem. Although Monado inherited
the correct name, the same old mistake was made in docs.
([!314](https://gitlab.freedesktop.org/monado/monado/merge_requests/314))
- build: For CMake rename (nearly) all build options so they begin with `XRT_`
and match the defines used in the source. You will probably want to clear
your build directory and reconfigure from scratch.
([!327](https://gitlab.freedesktop.org/monado/monado/merge_requests/327))
- ipc: Correctly set the shared semaphore value when creating it, the wrong value
resulted in the client not blocking in `xrWaitFrame`.
([!348](https://gitlab.freedesktop.org/monado/monado/merge_requests/348))
- ipc: Previously some arguments where dropped at swapchain creation time,
correct pass them between the client and server.
([!349](https://gitlab.freedesktop.org/monado/monado/merge_requests/349))
